- Abstract:
- The purpose of this presentation is to describe and demonstrate the technique for achieving the maximum roentgenographic detail in mammography. This objective is achieved with the aid of a middle-aged female clinical subject, a female mammography technician, x-rays, photographs and graphs. The program stresses the importance of obtaining radiographic detail in the early detection of breast cancer. In this presentation statistics regarding the incidence of breast cancer in the United States are presented first. Then the program traces the history of mammography and problems with the procedure which led to its disuse for a period of time. Then the presentation focuses on the procedure itself. According to this program three views are necessary for the full examination of the breast. These include the craniocaudal, mediolateral and axillary views. The proper positioning of the patient for each view is presented in detail and each view is described and the technique for taking the view demonstrated step-by-step. Proper coning, fine grain emulsion, low KVP and high MAS are described in relation to achieving maximum detail. The only variable is distance and the distance for each view is given. The processing of the film is then discussed. The importance of using a hand magnifying lens in the examination of the film is stressed.
